> test
  Run Bike Walk Drive
1   1    2    7     5
2   5    2    4     2
3   8    3    2     1

test2 <- test[, c(4,1,2,3)]
  Drive Run Bike Walk
1     5   1    2    7
2     2   5    2    4
3     1   8    3    2

if you want it in new data frame or

test <- test[, c(4,1,2,3)]

if you want to overwrite it.
